MixTTA: Low-Rank Cross-Channel Mixing for Reliable Test-Time Adaptation

Mansoo Jung, Youngwook Kim, Jungwoo Lee

Test-Time Adaptation (TTA) methods commonly update the affine parameters of normalization layers to adapt deployed models under distribution shifts. However, per-channel affine parameters perform axis-aligned scaling and shifting, making them geometrically incapable of correcting…Read more
